AUTOMATIC DISPENSER.

Application led September 25, 1923.

= receptacle under the mouth of the dispenser and thus engage the valveoperating means to open the valve and dischargethe fluid and in thatkupon the removal of the receptacle, the valve is automatically closed.

Another object is the provision of a simple and efficient valveactuation mechanism including a spring operatedand free from anycomplicated system of levers or the like.

A further object is the provision of a dispenser which operates upon theplacement of a receptacle upon a flat platform with a slight downwardpressure applied thereon. lith the foregoing and other objects in viewthe invention consists in the combination of parts and in the details ofconstruction hereinafter described, a preferred embodiment thereof beingillustrated in the accompanying drawings, in which :e

Fig. 1 is a view in vertical section through the dispenser showing thesleeve valve in closed position and the dispenser in inopera* tiveposition;`

Fig 2 is a view in vertical section through the dispenser showing thesleeve valve in open position and the dispenser in operative position;

Serial No. 664,736.

Fig. 7 is a View in vertical section through the dispensing kpipeshowing a valve of the type illustrated in Fig. 5 located in the lowerportion of the pipe.

Referring more in detail to the drawings, the body 1 is made hollow toreceive the cylindrical sleeve valve 2 so mounted therein as to beslidable vertically. The sleeve valve 2 is partly hollow and is providedwith but two ports 4C, an inlet, and 5 an outlet, both being circularand adapted to register with those of the inlet nipple 6 and outletnipple 7, respectively.

The valve 2 is also provided with a valve stemA 3 which protrudesthrough a suitable opening in the upper part' of the body 1. Secured toand resting on this stem 3 is a substantially flat platform 10 adaptedto receive any suitable receptacle 11 to be filled. In the lowerportionv of the hollow body 1 is arranged a compression coil spring 12adapted to exert upward pressure on the valve 2, and normally retain thelatter in closed position. A suitably curved pipe 17 is attached to theoutlet'nipple 7 and is provided with a discharge opening 9.

Fig. 1 shows the spring 12 in extended position thus forcing the valvein closed position. As shown in Fig` 2, when downward pressure isapplied on the platform 10 the valve 2 is forced downwardly against theaction of the spring 12, and the inlet port 4; registers with that ofthe inlet nipple 6, while the outlet port 5y registers with that of theoutlet nipple 7, thus presenting a continuous passageway for the fluidintroduced through the nipple 6 to be discharged into the receptacle 11.

Upon the withdrawal of the downward pressure upon the platform 10, thecompression spring forces the valve 2 upwardly and Vthe vports 4 and 5out of registration with those of the nipples 6 and respectively, thusclosing the valve and stopping the flow of the fluid as shown in Fig 1.

As shown in Figs. 3, 4 and 5, I have provided several modifications ofthe valve and its means of actuation, the principle of oper- :ating thedevice by exerting a downward pressure on the platform receptacleremain- As shown in Fig. 3, when the receptacle 11 is placed upon theplatform 10 with a downward pressure the stem 13 by means of the plate14C compresses the spring 12 Vand pulls the angular arm 16 downwardlyrotating the valve 19 into open position with its port 2() inregistration with the flow of fluid from the inlet pipe 17 through thepipe 18 and out the discharge end 9. The valve may also be arranged inthe upper portion of the pipe 18 by merely lengthening the arm 16suitably connected to the valve so as to positively operate same.

As shown in Fig. 5 a modified form of my invent-ion comprises a valvecasing 22 extending through the upper horizontal portion of the pipe 17,the casing having ports 25 within the pipe 18 and adapted to registerwith the recess 211 in the reciprocatory valve 23. The arm 18 isprovided with an upright extension 18 extending through the lowerportion of casing 22 and connected to the valve.

lVhen the platform 10 is pressed downwardly the downward motion istransmitted through the arm 18 and its extension 18 to the valve 28against the action of a compression coil spring 26 between the valve 23and the bottom of the casing 22. This action bring the ports 24 and 25into registration, opening the valve and permitting the discharge of thefluid. Upon the release of the downward pressure on the platform 10, thespring 26 automatically forces the valve. upwardly into closed position.

As shown in Fig. 6 the upper portion of the pipe 17 may be provided witha. swivel joint at 30 in order that the discharge end of the pipe may beswung into different positions such as indicated in dotted lines for thepurpose of filling larger receptacles not adaptable to be placed on theplatform 10. Having so manipulated the device it is only necessary toapply pressure with the hand on the platform 10 to cause the liquid tobe dispensed.

lu all of the modifications presented the stem for supporting theplatform and in Figs. 1, 2 and 6 is the valve stem, is of a squarecross-section so as to lit the square aperture 29 in the top` plate 27fastened on the body 1 by the screws 28, as shown in detail in Figs. 6and 6a.

As shown in Fig. 7 the valve and its actuation mechanism of the typedisclosed in Fig. 5 may be arranged in the lower portion of thedispensing pipe.

Having thus described my invention, l. claim-g 1. A fluid dispensercomprising a body portion adapted to receive a reciprocatory sleevevalve, spring means for normally retaining said valve in upward andclosed position, said valve having integrally attached therewith areceptacle platform, said valve being adapted to open upon a downwardpressure on said platform and to close automatically upon the release ofsaid pressure, the entire valve actuation mechanism operating in avertical plane.

2. A fluid dispenser comprising a body portion adapted to receive ahollow sleeve valve, spring means for normally retaining said valve inupward and closed position, Said body and valve having inlet ports, saidvalve having a stem carrying a receptacle platform, a pipe leading fromsaid body outlet port to a point adjacent said platform said valve beingadapted to open upon a downward pressure on said platform and to closeautomatically upon the release of said pressure.

3. A fluid dispenser comprising a body portion adapted to receive ahollow sleeve valve, spring means for normally retaining said valve inupward and closed position, said body and valve having inlet ports, saidvalve having a stem carrying a receptacle platform, a pipe leading fromsaid body outlet port to a point adjacent said platform said valve beingadapted to open upon a downward pressure on said platform and to closeautomatically upon the release of said pressure, said pipe beingprovided with a swivel joint near its upper portion.

4. A fluid dispenser comprising a body portion adapted to receive ahollow sleeve valve, spring means for normally retaining said valve inupward and closed position, said body and valve having inlet ports, saidvalve having a stem carrying a receptacle platform, a pipe leading fromsaid body outlet port to a point adjacent said platform said valve beingadapted to open upon a donward pressure on said platform and to closeautomatically upon the release of said pressure, said pipe beingprovided with a swivel joint near its upper portion, said valve bodyhaving a top plate with a square aperture, said valve stem being ofsquare cross section in accordance with said aperture to preventrotation of the valve' and non-alignment of the several valve ports withthose of the valve body.

In testimony whereof I affix my signature.
